A Novel Low-Cost Beam Steering Method Using Dispersive Superstrate

Beam steering is widely used in highly directional antenna systems and is generally done by using phase shifters or by changing the antenna elements. In this paper, a different technique for beam steering is presented. An antenna with a dispersive superstrate is able to steer the beam effectively. With this system, beam is steered 17° within 52 MHz bandwidth. The system is analyzed using CST Microwave Studio.
